| Hazard Information | Back Directory | [Preparation]
2-(2-Sulfo-4-nitrostyryl)-5-aminobenzenesulfonic acid diazo, coupled with phenol, then methylation, will the Nitro reduction, product diazo, and 5-Amino-7-ehtoxy-2-naphthalenesulfonic acid coupling, its product to diazo, and 3-(5-Hydroxy-7-sulfonaphthalen-2-ylamino)benzoic acid?coupling, and finally into copper complex. In the copper complexation processes, b oxygen radicals may be hydroxyl replaced. | [Properties and Applications]
dark green. Soluble in water for the green, not soluble in alcohol. The strong sulfuric acid for brown and yellow green, shallow blue light green for diluted. The dye solution to join strong hydrochloric acid have blue-ray gray precipitation; Add thick sodium hydroxide solution have yellow olive green precipitation.
